The `sash frame 10 supports 0.11,@ 0r more vPanes 0f glass 14 achnhavis the marginal edges thereof seated in ,an Vinvvardly"open ing recess which constitutes ma Yglazing Vchannel `1S. The sash frame 10 is adapted to be secured in the opening 11 of the mounting frame 12 by clamping the same to the flange formation 13 which extends inwardly of the sill 16 in the plane of the opening 11 and which provides a rigid support for mounting the sash.

The sash frame is formed of shaped sheet metal, for example stainless steel. Preferably, a single piece or plate is bent and welded as shown in the drawings so as to provide a hollow main frame section 17 of rectangular cross section having an outer face member 18, a peripheral outer edge face member 19 and an inside edge face member 28 with the marginal portions of the plate from which the frame is formed being brought together to form a double plate web section 21, 22 which extends inwardly normal to the two inside face forming sections 23 and 24 of the main frame section 17. The Web forming plate portions 21 and 22 have their free edges turned in opposite directions to form hook-like shoulder members 25 and 26 defining the inner limits of the frame 10. The plate portions 21 and 22 may be welded together to form a relatively rigid weblike divider member between the glazing channel which is formed by the inner wall section 23 and the plate portion 21 and the recess on the other side of the web formation 21, 22 which is defined by the inner wall section 24 and the adjacent plate portions 22 and which is adapted to receive the supporting flange member 13 of the mounting frame l2. The web section 21, 22 is provided with peripherally spaced pairs of struck-out tongues 27 and 28 with the tongues of each pair thereof struck-out in opposite directions so as to form hooks or anchor members for a purpose which will be described.

The frame 10 is constructed to be initially positioned in the opening 11 and is provided with a weatherstrip 30 of rubber or other compressible and resilient material which may be secured on the inside wall section 24 so that it is interposed between the wall section 24 and the outside face of the supporting flange 13, the weatherstrip 30 forming with the wall section 24 and the flange 13, when tightly drawn against the latter, a weatherproof seal.

The frame 10 is secured in rigid relation on the flange 13 with the outside face of the web plate 22 in confronting relation with the edge face l1' (FIGURE 2) which defines the opening 11 by means of a plurality of fastener elements 31 (FIGURE 5) which are arranged in spaced relation about the periphery of the frame. Each of the fastener elements 31 comprises a relatively short section of extruded aluminum or other suitable material which has a generally T-shaped cross section with a base plate forming member 32 having portions of unequal size on opposite sides of an angularly related stem or flange member 33. The fasteners are seated as shown in FIG- URE 2 with the base plate member 32 having the edge of the short portion engaged beneath a downwardly struck tongue 28 in the web plate 21, 22 and the opposite edge on the longer portion thereof engaged behind the hook or shoulder formation 26 at the inner edge of web plate 21, 22. The stem or flange member 33 extends parallel with the inside face 35 of the supporting flange member 13 and engages against a liller strip 36. The base plate member 32 is provided with a struck-out tongue 37 adjacent the edge thereof which is inclined in the direction of the member 33 and cut back to provide an abutment edge 38 for cooperation with a tool 40 (FIGURE 7) by means of which the fastener 31 is forced into position on the web member 22 in a manner which will be hereinafter described and which results in compressing the weatherstrip 30. The outside corners of the base plate member 32 may be cut away as shown.

After the sash frame 10 is installed in the opening and secured to the supporting flange 13, the glass pane 14 is positioned in the glazing channel 15 and secured therein by a plurality of peripherally spaced fastening or clamping elements 41 which are of substantially the same construction and may be the same material as the fastening elements 31, having a generally T-shaped cross sect-ion with a base plate member 42 and an angularly related stem-forming flange member 43. The base plate member 42 is adapted to be hooked beneath an upwardly struck tongue 27 in the weh member 21, 22 and having its opposite edge hooked behind the edge flange 25 of the plate member 21. The upstanding stem or flange member 43 (as shown in FIGURE 2) of the fastener 41 engages against a glazing bar member 44 of metal or other rigid material which forms the inside wall of the glazing channel 15. The glass pane 14 has its edge seated in the glazing channel 15 between a pair of glazing strips 45 and 46 which are compressed sufliciently to grip the glass and hold the glass pane 14 in position when the fasteners 41 are properly seated relative to the frame 10. Each of the fasteners 41 is provided with a struck-out tongue 47 adjacent the edge of the base plate member 42 which is cut off at the edge to form an abutment 48 for cooperation with the tool 40, which is used to install the fastener elements 41 as well as the fastener elements 31. The outside corners of the base plate member 42 may be cut away as shown. A channel-shaped inside cover or trim member 49 is provided which has its edges toed inwardly soI as to snap over the rounded edge portions 50 and 51 of the filler strip 36 and the glazing bar member 44.

The tool 40 which is provided for use in installing the fastener elements 31 and 41 is illustrated in FIGURE 7. It comprises a llat metal strip having a generally L-shaped slot 52 in the one end with the one leg 53 of t-he slot extending transversely of the long axis of the tool and the other leg 54 extending longitudinally and forming a mouth or opening therefor with the end portions of the tool at 55 being tapered or rounded as shown to form a hookshaped portion and the opposite portion 56 being rounded on its inside edge at 57'. The tool 4t) is employed as illus trated in FIGURE 8 to install the fastener elements 31. The fastener element 31 is placed in the position shown in FIGURE 8 with the inner margin of the base plate 32 in position to slide beneath the anchoring tongue 28 and the stem or flange member 33 engaging the lller strip 36. The tool is positioned as shown in FIGURE 8 with the hook portion 55 inside the 'flange 25 and the end portion 56 engaged against the abutment edge 38 of the tongue 37. The tool is rotated about the flange 25 as a pivot to force the base plate member 32 into the position shown in FIGURE 2 so that its edge engages the inside face of the flange 26 thereby compressing the weatherstrip 30 and securing the frame in tightly sealed relation to the flange 13 when all of the fastener elements 31 are installed about the periphery thereof.

lFastener elements 41 are positioned and moved into their final location by use of the tool 4) by a similar operation as illustrated in FIGURE 9. After the fastener 41 is positioned as shown in FIGURE 9, the hook portion 55 of the tool 40 is engaged behind the downwardly turned flange and the opposite end portion 54 is engaged with the abutment edge 48 of the upwardly struck tongue 47 on the base plate member. The tool is pivoted about the flange 26 to force the fastener into position thereby compressing the glazing strips 45 and 46.

The frame 10 may be employed in an opening of substantial size so as to make it desirable to divide the sash for installation of panes of a size smaller than the opening. As shown in FIGURE l, the sash may be divided by vertical rails 60 which may have the same configuration `as the exterior portion of the frame 10 (FIGURE 10), except that two glazing channels 61 and 62 of equal size will be provided for receiving the glass panes 14 with the panes having their edges seated between compressible glazing strips 45 and 46 which are held under compression by the glazing bar member 44. A plurality of the fastener elements 41 `are installed, with the use of the tool 49, in spaced relation along the rail and covered by a trim strip 63 of channel-shaped cross section.
